  • Publication number: 20230168217
    Abstract: According to an example aspect of the present invention, there is provided a disposable multilayer test strip comprising a substrate onto which is deposited an electrode assembly comprising a carbon-based working electrode, a carbon-based counter electrode, a pseudoreference electrode, wherein the pseudo reference electrode, the working electrode and the counter electrode, are arranged adjacent to each other in the same plane, contacts for contacting the electrodes directly to a voltage supply, and the test strip further comprises a permselective membrane layer. The electrodes of the electrode assembly layer are electrically separated from one another and said electrode assembly layer is positioned between the substrate and the permselective membrane layer. The permselective membrane has a structure adapted to allow passage of one or more electronically neutral analytes in a sample to be analysed across the permselective membrane to the electrode assembly.

  • Publication number: 20150261264
    Abstract: The present invention discloses a touch interface device for numerous applications and also a principle to store the device in a compact form. The device includes a flexible touch sensitive film which can be enclosed into a casing when stored, and removed, either fully or partially, from the casing when in use. The film may be manufactured by using High Aspect Ratio Molecular Structures. Touch Driving, Sensing and Communication Modules, separate or combined, can be attached to the touch sensitive film in order to transmit a raw touch signal to Touch Processing and Communication Modules, either separate or combined, and then as further processed, to a desired CPU or computer. The casing may also house an internal projector for displaying information. Furthermore, haptic feedback can be generated via the touch sensitive film as well.
